HMNC POWER-shows harmonic power contai n ed in the X marker band. If the a
band iSilot active. the power in all 20 harmonics is calculated. Harmonics
that fall outside the display scale are not included in the calculation. This
calculation is deactivated by pressing CALC OFF. The harmonic power
readout is in volts squared (or volts squared seconds for ESD units). Referto
the power softkey for other power calculations.
The label on the H M NC POWER readout depends on the trace units. HEG
indicates harmonic energy. HSM indicates harmonic sum, and HPR indi­
cates harmonic power.
MRKR -> PEAK-moves the marker to the highest amplitude point on the active
trace. If two or more points are at the highest amplitude, the marker moves
to the leftmost point.
POWER-shows the power in the area contained by the X marker band. If the marker
is not active, the power in the entire trace is displayed. If Just the single X
marker is active, the power at that marker position is displayed. An X-band
causes POWER to show the power contained in that band.
For non-frequency dornaln displays and unitiess frequency displays,
POWER calculates the linear sum of magnitudes and displays the result in
the active units. For frequency domain displays with the ESD unit selected,
POWER computes energy and displays the result in volts (peak) squared
seconds.
For frequency domain displays with all units other than ESD, POWER com­
putes power and displays the result in volts (rms) squared. For all frequency
domain displays with band markers, POWER compensates for the effects
of Hann and Flat top windows.
RETURN-redisplays the previous menu.
SBAND INCRMT --used to enter the sideband increment for the sideband markers.
The increment calculates and marks the first 10 sidebands on both sides of
the fundamental. The default value is 2.5 kHz.
SBAND ON-activates the sideband marker and displays its menu. This marker
shows a fundamental frequency and its first 10 sidebands. The fundamental
is entered with FNDMTL FREQ, and the sideband increment is entered
with SBAND INCRMT.
SBAND POWER-shows power in the sidebands identified by the sideband markers.
If an X marker is active, the sideband power inside the band is shown. The
calculation is deactivated by pressing CALC OFF. This marker function
reads out in volts squared (or volts squared seconds for ESD units). See the
POWER softkey for other power calculations.
The label on the sideband power readout depends on the trace units. SEG
indicates sideband energy; SSM indicates sideband summation; SPR indi­
cates sideband power.
SLOPE-shows the slope of the active trace at the current X marker position. If the X
marker band is active, the H P 3562A calculates the least squares average
of the area in the band and shows its slope.
